All-Aluminum Evaporator Coil

The Goodman 4 Ton Air Handler features a factory-installed 3/8-inch evaporator coil with all-aluminum tubing and high-performance coated fin stock. The coil mounting track allows convenient repositioning during qualifying installations.

The high-efficiency evaporator coil supports heat transfer when properly matched with compatible outdoor HVAC equipment. Final efficiency and performance depend on the complete AHRI-rated system combination.

Multi-Position Residential Installation

The multi-position design provides installation flexibility for compatible residential HVAC applications. The unit also includes primary and secondary drain connections located in a high-temperature plastic drain pan.

Galvanized-steel construction provides a durable cabinet, while easy service access helps qualified technicians complete installation, inspection, and maintenance procedures.

Low Cabinet Air Leakage

The cabinet is designed for air leakage below 2.0% at 1.0 inch H2O and below 1.4% at 0.5 inch H2O when tested according to ASHRAE Standard 193.

Controlling cabinet air leakage can help support proper airflow when the Goodman 4 Ton Air Handler is correctly installed and configured as part of a compatible HVAC system.

Optional Electric Heat Kits

This air handler supports compatible electric heater kit options from 3 kW to 25 kW, depending on the approved equipment configuration and electrical requirements of the installation.

The installer must verify the appropriate heater kit, electrical service, circuit protection, wiring requirements, and applicable local codes before adding electric heat.

Verify Equipment Compatibility

The Goodman 4 Ton Air Handler must be properly matched with the outdoor condenser or heat pump, refrigerant line set, thermostat, electrical components, and optional heat kit.

Do not select indoor HVAC equipment based only on nominal tonnage. A qualified professional should verify the complete system combination, AHRI certification, airflow requirements, electrical specifications, refrigerant compatibility, and installation configuration before ordering.

Professional Installation Required

Installation must be completed by a qualified HVAC professional according to manufacturer instructions and applicable regulations. The installer should verify refrigerant connections, condensate drainage, electrical service, airflow settings, leak detection components, and overall system operation.
